Transcript of The Path of Red Blood Cells Through the Circulatory System

FIVE. The path of a red blood cell begins in the heart, the left ventricle contracts, pushing red blood cells into the aorta. ONE. The heart then pushes red blood cells into the aorta so the process of the cells traveling through a series of arteries can begin until it reaches a capillary. TWO. THREE. Once the blood cells have started to travel through the capillary, oxygen molecules detach from the red blood cells and slip across the capillary wall then break into body tissue. FOUR. Now deoxygenated blood finds its way to the heart. It then passes through veins to ultimately reach the right atrium. The de-oxygenated blood enters the right ventricle, which pumps it through the pulmonary arteries into the lungs, to pick up more oxygen. Oxygenated blood reenters the left atrium, to move into the left ventricle. The Journey of Red Blood Cells Through the CirculatorySystem SIX. Now the blood cells begin there journey again.
